Wei Huang b6bb424b40 KVM: x86/vPMU: Fix unnecessary signed extension for AMD PERFCTRn ...

According to AMD programmer's manual, AMD PERFCTRn is 64-bit MSR which,
unlike Intel perf counters, doesn't require signed extension. This
patch removes the unnecessary conversion in SVM vPMU code when PERFCTRn
is being updated.
